IM PROVED LUBRICATING APPARATS.

Specification forming part of Letters Patent No. 56,306, dated July 10,1866.

To all whom 'it may concern:

Be it known that we, JAMES L. WIGGIN and EBEN FOLSOM, of South NewMarket, in the county of Rockingham and State of New Ham pshire, haveinvented a new and useful Apparatus for Lubricating the Journal of aShaft, and we do hereby declare the saine to be fully described in thefollowing specification, and represented in the accompanying drawings,of which- Figure l is a vertical section of such apparatus. Fig. 2represents it as applied to a shaft journal and box.

4In such drawings, A denotes an inverted bottle or vessel provided witha cork or stopper, B. A tube, C, closed at its upper end and open at itslower end, goes through the cork and extends a short distance above it.This tube has a 'orarnen or minute hole, a, made in its top. It also hasanother such hole made in its side, and in that part of the tube whichprojects into the vessel A.

The tube G, when the apparatus is in use, is to extend into the cap of ajournal-box, and so as to reach nearly down to the journal. The passagein the cap for the reception of the tube should extend quite down to thejournal, the same being as represented in Fig. 2, in which D is thejournal, c the cap, and E the boX.

Preparatory to the apparatus being so applied to the cap the vessel Ashould be charged with oil, or a lubricating matter, or uid.

The shaft, while in revolution, will cause air to pass up the tube C,and through the forainen a in its top, whereby a small am'ount of oilwill be caused to pass through the foralnen I) into the tube, down whichit will tiow and upon thejournal.

0n the journal ceasing to revolve there will be no such forcing of airup the tube, and consequently no discharge of oil from the vessel.

We claim- The shaft-lubricating apparatus, made in manner and forapplication toa shaft bearing or box, substantially as hereinbet'oredescribed.
